MACHINE FOR MAKING SPLIT EINGS.

Specification of Letters Patent No. 33,125, dated. August 20, 1861.

To all whom it may concern:

Be it known that I, EDWIN H. PERRY, of the city and county of Providence, in the State of Rhode Island, have invented a new and useful Machine for lVIaking Split Rings; and I do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, andexact description thereof.

Figure 1 is a perspective view of the whole machine. Figs. 2, 3 4, 5, 6, 7, 8, 9 and 10 are detailed parts to be referred to hereafter.

The article which is known to the trade by the name of split ring has hitherto beenmade exclusively by hand labor and by the following process. A piece of wire of a length sufhcient for the number of rings to be made is woundspirally around a. mandrel; :the wire is then out into pieces of two conrolutions each and each piece is then sepairai'ely subjected to the action of a swing or die and former which impart-s to it the finished shape.

The machine which is the subject of my invention embraces in its organization all the operations necessary to convert any length of wire into finished rings without the intervention of manual labor.

In the accompanying drawings A is the platform of the table upon which the diiferout parts of the machine are placed. The shaft E, having arranged upon it the cams and toothed wheels for communicating the various motions presently to be described is placed in suitable bearing standards BB above, but parallel to the face of the tableA.

Suppose now that a long coil of common annealed wire of any size suitable to the capacity of the machine is led between the upright straightening pins in the plate C Fig. 3) and also between the guide pins a a in the arm 1 the extremity of the wire being held against the winding spindle 2 (Figs. 1 and by the clamp jaw 7) (Fig. 2) hereafter to be described.

hen the shaft B is revolved the teeth of the beveled wheel D will cause the pinion E and the winding spindle to which it is keyed to be rotated many times and fractions of times as the teeth on the wheel B are in excess of those on the pinion E. The effect of the rotation of the pinion E is, in the instance here shown to wind the wire nearly twice around the spindle and when this has been accomplished the wheel D has arrived in the course of its revolution to that part of its face at the poin't'c (Fig. 1) from which up to the point (Z the teethhave been stripped as shown in Fig. 1. While the wheel D is passing through the distance from 0 to d the pinion E, and =spindle2, will be at rest. An oppor tunity is thus given for the cutter F (operated by the eccentric camGyderiving its motion from the upright shaft H, which is driven by the bevel gears I 1) to dart for-- Ward and cutthe coil from the wire. As the cutter commencesits retreat the cam J acts upon the head of the spindle (Fig. caiising it to descend and deposit the coil in the barrel 7c of the revolving carrier wheel K. A spring 3 returns the spindle to its first position as soon as it is relieved from the action of the cam J. i

The carrier consists of three radial arms as shown in Fig. 1'equi-distant from each other. Near the extremity of each arm and at points in the same circle from the axis of the carrier as a center, is placed a cylindrical barrel (Fig-10) within which a coil can be deposited and which coil will be sustained by the pressure of its convolutions against the interior surface of the barrel.

The wheel I) is now supposed to have arrived at the point d and a fresh coil of wire is being wound around the spindle. While this operation is going on the carrier K is by means of a train of wheels located beneath the platform A rotated one third of a revolution by means of a geared sector or its equivalent (Fi keyed to the upright shaft H and made to engage with the teeth of a train of wheels operating the carrier K at such intervals of time and during a period long enough to effect the one third revolution of the carrier while one complete revolution of the driving shaft is being made. The partial revolution of the carrier plate brings the barrel is with the coil deposited in it to a point directly beneath the plunger L while a second barrel is is brought to the position beneath the spindle 2 just occupied by it.

The plunger L works in suitableguides and has an upward and downward movement communicated to it by means of the eccentric wheel and strap M. Coincidently with the downward motion of the plunger and operated by a pin projecting from the face of the eccentric wheel M, through the intervention of the levers O and O and the connecting rod P (Fig. 6) the swage or plunger N located beneath the platform is made to rise and enter the bottom of the barrel is filling the interior of the coil and bearing against the face of the plunger L the spring 5-(Fig. 6) allowing the swage N to yield to the pressure of the plunger L if necessary. The result of these two opposing forces acting upon the coil confined as it is on all sides within the barrel 7c is to swage it into the proper shape. The carrier, by the same means as before described rotates another one third of a circle as soon as the plunger L and die N are returned to their respective places, the effect of which partial rotation is to bring the barrel h with the ring within it to a point directly beneath the clearing punch Q which on being forced downward by the cam Q clears the barrel of the finished ring.

Simultaneously with each partial rotation of the carrier K and while the plunger L and clearing punch Q are acting a fresh coil of wire is being wound upon the spindle 2, so that when the machine is in full operation a finished ring is delivered at every revolution of the main shaft 13.

The devices by which the wire is clamped against the spindle 2 while the coil is being wound, and released therefrom at the moment it is time for the spindle to deposit the coil in the carrier are as follows.

The rod R Fig. 2 passes through the aXis of the pinion E (Fig. 1) the lower extremity of which R by reason of its form as shown in Fig. 2 describes a circle around the wind ing spindle. The jaw b pivoted at I) just outside of the winding spindle has the arm S which works it jointed to the lower extremity of the rod R. A coiled spring is wound around the upper part of the rod R abovethe top of the face of the pinion E as shown in Fig. 1 the constant tendency of which is to pull the arm S (Fig. 2), in the direction of the arrow'and thereby cause the clamp Z) to hold the wire against the spindle.

The grasp of the clamp continues so long as the coil is being wound but as soon as the spindle has made its prescribed number .of revolutions as already'described a cam T in the main shaft acts upon the head of the rod R and forcing it downward relaxes the pressure of the clamp. In order then that the end of the length of wire to be manufactured shall not embarrass the action of the spindle as it descends to deposit the coil in the barrel is the bell crank arm 1 (Fig. 3) is moved in the direction of the arrow by the wedge face arm 4:, (Fig. 3) which works in the slotted end 6 of the bell crank 1 and is made to act at each descent of the clearing punch Q 'to the shank of which the arm 4 is attached. 7 I

As the descent of the clearing punch is coincident in point of time with the retreat of the cutter F it is obvious that the end of the wire to be fed to the machine will ibe i 'i moved by the guiding pins 64 a between which it passes in a direction away from the r winding spindle. As the main shaft revolves the clearing punch (Fig. 1) risesby.

the action of the spring Uv and brings the end of the wire again against the spindle. The clamp Z) then holds it fast and the opera tions described, are repeated. 7 r it 1s obvious that the mode of operation which I have described may be embodied in.v

a variety of forms and arranged to exhibit the same princlple in a variety of ways. i I

do not therefore limit myself to the form, or

arrangement of the several parts as de scribed but 1 intend to include all mere.

variations of form or of arrangen'ient producing substantially the same result b equivalent means.

What I claim as my invention and desi to secure by Letters Patent 1s 1. The mode of operation substantially spec fied by means of which a wire of-1n-- definite length is wound in successive coils of two or more convolutions and eaclrcoil:

ioo

its equivalent for transporting the coil-the employment of the punches L and N or theirv equivalents substantially as described for the purposes specified. V

i. In combinatlon with a spindle or 1ts equivalent for winding the coils the employ ment of a clamp or its equivalent substantially as described for holding the wire.

against the spindle while it is being wound in the manner and on the principle substantially as herein set forth.

5. The mode of operation substantially as 3 described by means of which the endof the wire after a coil has been cut off is prevented from bearlng against the winding splndle while it is discharging the coil as herein set forth.
